Service-life prediction of reinforced concrete structures through a chloride diffusion model

Abstract

Most of the pathologies presented in the concrete structures are because of the corrosion process. Herein, a methodology that allows doing a quantitative estimation of the service life of concrete structures is presented. This methodology uses chloride diffusion models. The application of the methodology to a study case is presented. In this study case were considered all the prescriptions of the durability standards. The results of the estimations 2014of the service life of the structure are compared with the recommendations commonly used, showing the necessity of service life studies.
